IMPROVEMENT IN LQADING AND UNLQADING WAGONS.

Specification forming part of Letters Patent No. HS/l, dated Dscenicr 524, 1872.

To all whom it may concern:

'Be it known that I, RICHARD THRELFALL, ot' Centreville, Alameda county, State ot' Galiiornia, have invented Improvements in Unloading Header-lfvfagons; and I do hereby declare the following description and accompanying drawing are sut'ticient to enable any person skilled in the art or science to which it mostnearly appertains to make and use my said invention or improvements without further invention or experiment.

My invention rela-tes to an improved method and arrangement for unloading the wagons which run between the header and the thrash.- in g-machine for the purpose of conveying the cut grain to the thrasher or stack.

Eeretofore this work has usually been done with forks operated from a.swinging derrick or crane; but this method ot' unloading is too slow to keep the thrasher supplied with a uniform feed. l

My invention contemplates an arrangement whereby the entire wagon-load of cut grain can be unloaded at one operation, so as to perinit the Work of. carrying the out grain from the header to the thrasher to be done by a less number of wagons,while the feed of the thrashin g-machine is rendered more uniform, and the grain will be less liable to be cracked.

In order to more fully illustrate and explain my invention, reference is had to the accompanying drawing forming a part of this specilication, in which- Figure l is a perspective view of the nia-- chine. y

A represents a wagon, such as is usually employed for conveying the grain from a header to the thrashing-machine. B is a swinging crane or derrick, such as is frequently used for unloading the header-wagon by means of hay or grain forks. Instead of the hay or grain fork I propose to employ a netting, .(5, or other closed piece of fabric large enough to cover the entire bottom and sides ofthe wagon. The cut grain is then taken from the header and placed in the wagon upon the netting or other false bottom O until the wagon is loaded.

Vhen the wagon has arrived at the derrick B the loop d, on one side ofthe netting or false bottom U, is caught in the hook c which depends from the cord and pulley f of the derrick, while the tWo opposite corners are caught up and secured to a suitable det-aching apparatus, y, thus forming a large bag, in which the load of grain is contained. rIlle derrickis then employed to lift the load of grain thus conditioned and swin git around above the feeding table or stack, upon which itis dumped by drawing upon the cord t', which unoouples the detachin g apparatus and releases the grain.

Any of the usual styles of detaching apparatus can be used, and any pliable yielding false bottom will answer.

By this means I provide a simple and effective arrangement for unloading wagons, which will save time, labor, and expense, and at the same time greatly facilitate and benefit the thrashing operation.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. rEhe false bottom C, in combination withv the wagon A and derrick B, substantially as and for the purpose above described.

2. The false bottom C with its loop d, in combination with the hook e and detachin g apparatus g, substantially as and for the purpose nsi
